What is "neuromyotonia"

n. Spontaneous muscular activity, usually as a result of a fault in the immune system

Neuromyotonia (NMT), also known as Isaacs Syndrome and Isaacs-Merton syndrome, is a form of peripheral nerve hyperexcitability that causes spontaneous muscular activity resulting from repetitive motor unit action potentials of peripheral origin. Prevalence is unknown but 100—200 cases have been reported so far.
